Which part of the respiratory system is the site of exchange of gases in humans?

Last Updated:

Built around the concept in “Which part of the respiratory system is the site of exchange of gases in humans?”, this bilingual General Science item checks whether a learner can connect a scientific term with its exact property, mechanism or function. The verified answer is Alveoli.

AAlveoli
BLarynx
CBronchi
DTrachea
Correct Answer: AlveoliYour Answer: A

Explanation

Option A, Alveoli, matches the evidence in the stem. Gas exchange occurs across the thin walls of alveoli in the lungs. Similar organs and biomolecules may participate in the same body system but do not perform identical functions. The alternatives Larynx, Bronchi and Trachea are legitimate scientific terms, but each belongs to a different function, property, material or context. A useful verification is to state the definition in one sentence and ask whether the selected option satisfies every part of it.

Important Notes

  • Verified answer: Alveoli; option A, zero-based index
  • Core scientific fact: Gas exchange occurs across the thin walls of alveoli in the lungs.
  • Distractors Larynx, Bronchi, Trachea represent different scientific associations.
  • Revision pair: “Which part of the respiratory system is the site of exchange of gases in humans? — Alveoli”.

Common questions and clear answers for this topic.

Which part of the respiratory system is the site of exchange of gases in humans?

Alveoli. Gas exchange occurs across the thin walls of alveoli in the lungs.

Which concept should be used to solve this item?

Use the defining property and mechanism from biology.

Why are the other options unsuitable?

Larynx, Bronchi, Trachea belong to different functions, properties or contexts.

How should this fact be revised?

Connect “Which part of the respiratory system is the site of exchange of gases in humans?” with Alveoli and the supporting mechanism.

What is General Science and which topics are important for competitive exams?

General Science covers basic concepts in Physics, Chemistry, Biology, and Earth Science. It is an important section in competitive exams like SSC CGL, UPSC Prelims, Railway NTPC, and Defence exams. Questions include scientific laws, inventions, human body systems, chemical reactions, and everyday science phenomena. NCERT Science books from Class 6 to 10 are recommended.

What are Newton's Laws of Motion?

Newton's Three Laws of Motion: 1) First Law (Law of Inertia) - An object remains at rest or in uniform motion unless acted upon by an external force. 2) Second Law - Force equals mass times acceleration (F=ma). 3) Third Law - For every action there is an equal and opposite reaction. These laws are fundamental to Physics and frequently asked in SSC CGL, Railway, and NDA exams.
